BACKGROUND Major surgery might have a modulating effect on nocturnal breathing patterns. The incidence and course of perioperative sleep-disordered breathing in individuals without a previous diagnosis of obstructive sleep apnea has not been investigated sufficiently so far. METHODS In this study, polygraphic recordings have been obtained from 37 inpatients without a diagnosis of obstructive ...

Introduction: Annually, millions of Muslims all over the world observe the fasting rules based on its measures; this highlights the importance of studies in this field as a worthwhile model for intermittent fasting. It is obvious that changes in lifestyle over fasting have outstanding effects on physiological parameters. The current study was carried out to investigate the IOP and serum electro...

OBJECTIVE To evaluate the effects of study participation per se at the beginning of a sleep extension trial between screening, randomization, and the run-in visit. DESIGN Subjects were screened, returned for randomization (Comparison vs. Intervention) after 81 days (median), and attended run-in visit 121 days later. SETTING Outpatient. PATIENTS Obese (N = 125; M/F, 30/95; Blacks/Whites/Ot...

For several weeks, three ponies kept in an environment with controlled light and temperature, were studied for behaviour (time spent in recumbency and time required to consume hay or oats) and for electrical activity of the brain (cortical and sub-cortical) during the night phase of the circadian rhythm. Recumbency was adopted by all the ponies for six or seven periods during the night. With a ...

Circadian rhythms in Syrian hamsters can be phase advanced by activity or arousal stimulated during the daily rest phase ("subjective day"). A widely used method for stimulating activity is confinement to a novel wheel. Some hamsters decline to run, and some procedures may reduce the probability of running. The authors evaluated food deprivation (FD) as a method to promote running. Given eviden...

although several studies have investigated the effects of ramadan fasting on diabetic patients, the exact impacts on diabetes control have not been well elucidated yet. there are neither precise quantitative criteria nor clear guidelines regarding ramadan fasting for diabetic patients. this review aimed to discuss the results of previous studies. the neglected points in performed studies should...

Cross-sectional evidence suggests associations between sleep duration and levels of the inflammatory markers, C-reactive protein and interleukin-6. This longitudinal study uses data from the London-based Whitehall II study to examine whether changes in sleep duration are associated with average levels of inflammation from 2 measures 5 years apart. Sleep duration (≤5, 6, 7, 8, ≥9 hours on an ave...

Breakfast omission is associated with obesity and CVD/diabetes, but the acute effects of extended morning fasting upon subsequent energy intake and metabolic/hormonal responses have received less attention. In a randomised cross-over design, thirty-five lean men (n 14) and women (n 21) extended their overnight fast or ingested a typical carbohydrate-rich breakfast in quantities relative to RMR ...
